Abstract (en)
The present invention is related to a method and apparatus for adjusting a field of view for exposure of an X-ray system and to an X-ray system. The method comprises: capturing an image of a patient on an examining table 204 of the X-ray system by an image sensor 208, wherein the image sensor 208 is placed at a predetermined position in the X-ray system; displaying the captured image on a display 206 for selection of a region of interest or a point of interest by a user on the image; automatically determining a target position of an X-ray source 202 in response to the selection of the region of interest or the point of interest on the image, wherein a desired field of view for exposure covering the region of interest or the point of interest is obtained when the X-ray source 202 is located at the target position; and automatically locating the X-ray source 202 at the target position in response to the determination of the target position. Automatic adjustment of a field of view for exposure can be achieved by the present invention.
